[0030] It should be noted that in the commercial vehicle electronic exterior rearview mirror vehicle display system, the concept of "electronic exterior rearview mirror" is the industry name for each camera in the following embodiments.

[0031] Example 1

[0032] like Figure 1 As shown, Figure 1 A schematic structural diagram of a vehicle display system for an electronic exterior rearview mirror for a commercial vehicle is shown as an exemplary embodiment of the present application. The system is applicable to the installation structure of a rearview mirror for a commercial vehicle, wherein CAM indicates a camera structure.

[0033] The system includes a first wide-angle fisheye camera 10 , a second wide-angle fisheye camera 20 , a first rear-view camera 30 , a second rear-view camera 40 , a controller 50 , a first monitor 60 , and a second monitor 70 .

[0034] First, the arrangement of each camera is introduced. The first wide-angle fisheye camera 10 and the second wide-angle fisheye camera 20 are respectively installed at the A-pillar position in front of the left and right sides of the driver's position and illuminate downward; the first rear-view camera 30 and the second rear-view camera 40 are installed at the original reflector position of the commercial vehicle and illuminate backward.

[0035] The A-pillar position refers to the longitudinal structural pillars on both sides of the front of a commercial vehicle, between the front door and the windshield of the vehicle, and located on both sides of the vehicle body. They are usually part of the body structure, used to support the roof and provide stability and rigidity to the vehicle structure. The A-pillar plays an important role in vehicle safety and is usually one of the locations where airbags and vehicle collision protection systems are installed.

[0036] Further, the connection relationship of each component is described. The first wide-angle fisheye camera 10 is connected to the controller 50, which is then connected to the first monitor 60; the second wide-angle fisheye camera 20 is connected to the controller 50, which is then connected to the second monitor 70; the first rear-view camera 30 is connected to the controller 50, which is then connected to the first monitor 60; the second rear-view camera 40 is connected to the controller 50, which is then connected to the second monitor 70.

[0037] The commercial vehicle electronic exterior rearview mirror vehicle display system in the embodiment of the present application provides a display system structure of two rear-view cameras, two large-angle fisheye cameras, two monitors and a controller, which effectively assists the driver in driving. The provided arrangements and connection methods of the various cameras can meet the requirements of the commercial vehicle for the field of vision during driving and cover the blind spots of the commercial vehicle to the greatest extent, and display relevant information on the monitor in a clear manner, thereby improving the driver's driving safety. It is easy to install by fixing the arrangement in the original vehicle body position without the need to customize high-cost brackets. Compared with the current existing technology, this technical solution mainly solves technical problems such as blind spots and high costs of using more cameras, thereby providing a simple and low-cost electronic exterior rearview mirror system that meets the requirements of blind spots.

[0038] Example 2

[0039] The parameters and arrangement positions of the above-mentioned cameras are further described through the embodiments of the present application.

[0040] When arranging the cameras, the first wide angle fisheye camera 10 and the second wide angle fisheye camera 20 are located at the A-pillar position 1.5m-2m from the ground, and the specific situation depends on the design and height of the vehicle body. A possible implementation rule is given below for reference by those skilled in the art during implementation.

[0041] Among them, 1.5m-2m is the installation height of each large-angle fisheye camera. Because different fisheye cameras have different angles, the higher the camera is installed, the more fields of view can be seen on the left and right sides. In the project currently tested by the applicant, the installation height experiment is about 1.5m, while meeting the field of view required by regulations. If the client has a larger field of view requirement, and considering that commercial vehicles are generally not higher than 4.2m, the installation height can be increased to 2m. The client can adjust the installation height of each fisheye camera according to the specific situation.

[0042] In addition, the first rear-view camera and the second rear-view camera are installed at the original mirror position of the commercial vehicle and illuminate the rear, and the height is the same as the original rearview mirror height.

[0043] The imaging range of the first wide-angle fisheye camera 10 covers the blind field of the V and VI mirrors on the left side of the driver, and the imaging range of the second wide-angle fisheye camera 20 covers the blind field of the V and VI mirrors on the right side of the driver. The imaging range of the first rear-view camera 30 covers the field of view of the II and IV mirrors on the left side of the driver, and the imaging range of the second rear-view camera 40 covers the field of view of the II and IV mirrors on the right side of the driver.

[0044] like Figure 2 As shown, Figure 2 A schematic diagram of the display field of view of each monitor shown in an exemplary embodiment of the present application is shown.

[0045] The imaging range of the first wide-angle fisheye camera 10 is displayed on the top screen 11 of the first monitor 60, accounting for 1 / 4; the imaging range of the second wide-angle fisheye camera 20 is displayed on the top screen 21 of the second monitor 70, accounting for 1 / 4.

[0046] The imaging range of the first rear-view camera 30 is respectively displayed on the middle picture 12 and the bottom picture 13 of the first monitor 60, accounting for 1 / 2 and 1 / 4 respectively; the imaging range of the second rear-view camera 40 is respectively displayed on the middle picture 22 and the bottom picture 23 of the second monitor 70, accounting for 1 / 2 and 1 / 4 respectively.

[0047] like Figure 3 As shown, a single-side layout diagram of each camera is provided, wherein point A is a schematic installation position of the second widest angle fisheye camera 20, wherein the distance from the ground to the A-pillar is 1.5m-2m, and the specific situation depends on the design and height of the vehicle body.

[0048] like Figure 4 As shown, it provides the corresponding Figure 3 Schematic diagram of the shaded area. Point B indicates the driver's eye point, where 4.5m, R=2m, 3m, and 1.75m are the required values ​​for the field of view of commercial vehicles in GB15084-2022. The relevant content is "6.5.5.2, for vehicles with a ground clearance of more than 2.4m at any adjustment position of any part of the V-class mirror or its mounting bracket, the driver should be able to see the area defined by the following vertical planes on the horizontal road surface. Laterally, a parallel plane is drawn 4.5m outward from the plane described in 6.5.5.1. Backward, a parallel plane is drawn 1.75m behind the vertical plane passing through the driver's eye point. Forward, a parallel plane is drawn 3m in front of the vertical plane passing through the driver's eye point. This field of view can be provided by the front field of view device part."

[0049] In the embodiment of the present application, the components are connected by wire harnesses. The first wide-angle fisheye camera 10 is connected to the controller 50 by a wire harness, and the controller 50 is connected to the first monitor 60 by a wire harness; the second wide-angle fisheye camera 20 is connected to the controller 50 by a wire harness, and the controller 50 is connected to the second monitor 70 by a wire harness; the first rear-view camera 30 is connected to the controller 50 by a wire harness, and the controller 50 is connected to the first monitor 60 by a wire harness; the second rear-view camera 40 is connected to the controller 50 by a wire harness, and the controller 50 is connected to the second monitor 70 by a wire harness.

[0050] Regarding the fixing method, there is no need to customize expensive fixing brackets, and the first wide-angle fisheye camera 10 and the second wide-angle fisheye camera 20 are installed at the A-pillar position by gluing or brackets.

[0051] The beneficial effects of the embodiments of the present application are as follows. The blind spot problem is effectively solved by the layout of the camera, and the field of view is increased; a large-angle fisheye camera is used to cover the blind field of view of the single-side V and VI mirrors at the same time, and the corresponding blind field of view imaging and the rear-view camera imaging covering the single-side II and IV mirrors share a monitor on one side, that is, a relatively simple and low-cost method is adopted to solve the vehicle rear-view problem. By using a small number of cameras and monitors, and using a large-angle fisheye camera to cover multiple fields of view, the cost and installation complexity are reduced, and the structure is simple and the cost is low; there is no need to customize high-cost brackets and other costs, and it can be directly pasted on the body or punched on the car, and screwed; the layout of the camera also helps to cover the blind spot of the vehicle, and the wiring method is relatively clear, easy to understand and operate. Compared with the prior art, the superiority of this technical solution is mainly reflected in the cost and installation method. The existing system solution has more cameras and higher costs, and the installation requirements are increased, and specific brackets need to be customized. The system structure of this application can reduce costs and be easy to install. While ensuring that the field of view is met, it is easy to operate at the same time.

[0052] It can be applied in the fields of automotive engineering technology, electronic rearview mirror technology, display technology, etc. For example, it can be applied to auxiliary driving systems to solve the problem of blind spots in the driver's field of vision and improve driving safety. With the rapid development of the automotive industry, the technical application prospects and market demand of this utility model will continue to expand.
